7 fMy invention relates to: improvements in {clutchtransmissions, and it consists in the combinajions, constructions, and arrangeli f'm ents h rein'described'and claimed.

"8 An. object ofimy inventionis to provide a clutch transmissionparticularly adapted to i be used in connection.with head gates emfployed for irrigational purposes and similar uses, and in which novel'means is provided whereby a relatively heavyweight may be v releasingmechanism ,is 'used' whereby the lifted weight is suddenly freed and permltted r to id ropf'freely. i, 1

x 1 j'fA' further object is to provide a clutch 5 if transmission comprisi g in combination a V plurality of gears'whereby an object may be positiv'elymoved and'in which the releasing mechanismis 'constructedin-such a manner I that 'certain of the gear'elements may be sudv j den'ly thrownfjout'of mesh'bythe pulling:

videdwith 'bearings 6 for supporting a shaft 7'upon which a gear 8 and a worm gear 9 are mounted. The two-gears are fixed upon the shaft. The frame 1 may bean integralcon- 'stru'ction formed from cast material or the side portions may be'secured together by any H suitable means, such as welding and'the like.

I may also employ wood in lieu of metal in certain cases where I am confining the invention to light'work. i i

The casingmay be provided with lug portions 10 having openings 11 whereby the casing may be rigidly secured to any suitable supporting structure, as indicated at '12 in ltigure 6. The side portion 5' is provided with 05 21. pair of flanges 15 ,for' supportinga roller "14. A bar-15 is disposed'adjacent theroller 14 andbetween the flanges 13 and is provided with a rack'l 6 which is disposed in mesh with the gear '8. The "bar 15 is connected with a agate 17, see Figure 6." The roller provides non-frictional means against which "the bar may'slide and also holdsthe'r ackin proper relationwith its associated gear 8.-

The side portions3'and 5 are provided with openings 18 and 19, respectively, through which reduced shaftiportions 20 and 21 of a shaft 22 project.- The reduced shaft portions are slidably and rotatably mounted "within the openings. The'shaft 22 is provided with a worm 23 which'is normally disposed in mesh with the worm gear 9. A releasing memberc2 is hingedly mounted at 25 upon the side portions 2 and 3 and is provided with a recess 26, see Figure 3, for receiving the shaft20 when thereleasing memv her is positioned as shown in Figures 1 and 3. At this time one side of'the releasing member bears against the side portion 3' and the opposite sideof the member bears against the end ofithe shaft 22. V The releasing member 24 maybe lifted away from the shaft 20 'fb'rrleasing rm 3, 1 will be ex- -P1 ned later, p I I In Figure 6,1 have shown the gat 17 as I being: guided between channel members 27. These members may be associated with wall ,po ft ions' -28fwhich are preferably formed from cement jand the like. The walls pro- 00 "ter 29..
